Coating Machine's workflow
Apr 30,2021
Coating Machine roughly includes: coating, drying, hot pressing, cooling,... and other units
①Coating unit
Coating Machine is designed according to different machines, and the methods of coating and gluing include roller coating and knife coating. The glue-coated surface is also different on the cloth material, underneath or on the film. Different gluing methods make the glue penetrate on the substrate and form a film differently. Of course, there are differences in the adhesion effect. In addition, The presence or absence of lines on the coating wheel and the pattern of the lines will also affect the difficulty of applying glue and the form of glue coating (full coating, spot coating...). Coating wheels with special patterns and corresponding glues can even compound high-performance finished products, such as breathability and super soft hand feeling.
②Drying unit
The existence or length of the Coating Machine oven and the way of drying (hot air circulation or infrared assist) also have different designs depending on the selected model and roller or blade coating. The volatilization rate of the glue solvent is closely related to the drying conditions of the machine, so how to adjust to the appropriate temperature required by the material is essential for making good adhesion during bonding.
③Hot press unit
The size of the Coating Machine hot pressing wheel, the surface temperature, and the length of the pressing time will be related to the volatilization efficiency of the residual solvent, the activation degree of the glue and the quality of the bonding effect.
④Cooling unit
Before crimping, the laminated composite is cooled by the cooling wheel, which can promote the crystallization of the glue, improve the initial adhesion, and avoid the displacement of the laminated material during winding.
